Lower Limb Venous Insufficiency and the Effect of Radiofrequency Treatment Versus Open Surgery

May 10, 2023 updated by: Oskar Nelzén, University Hospital, Linkoeping

Lower Limb Venous Insufficiency and the Effect of Radiofrequency Treatment Versus Open Surgery. A 5-year Follow-up Using Duplex Ultrasound, Plethysmography, VCSS, AVVQ and EQ-5D

200 patients with insufficient great saphenous veins will be randomized to either radiofrequency ablation or high ligation/stripping (open surgery). They will be examined according to standardized examination protocol Venous Clinical Severity Score (VCSS), with duplex ultrasound and plethysmography pre- and postoperatively (1-month, 1-, 3 and 5 years). They are to fill questionnaires EuroQol 5 Dimensions (EQ-5D) and disease specific Aberdeen Varicose Vein Questionnaire (AVVQ).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Radiofrequency ablation
Treatment with radiofrequency ablation using radiofrequency ablation catheter. This intervention implies tumescent anesthesia.
Other Names:
  • Covidien ClosureFast Catheter (7cm)
Active Comparator: High ligation/stripping
Treatment with high ligation/stripping using a vein stripping catheter. This intervention implies general anesthesia.
Other Names:
  • Open surgery
